Time2023-12-12

The manufacturing of pressure vessels for mechanical equipment refers to closed devices that hold gases or liquids and bear a certain pressure.

       Mechanical Equipment ManufacturingPressure vessels refer to closed equipment that holds gases or liquids and bears a certain pressure.
Uses of Pressure Vessels
       Pressure VesselThe uses of pressure vessels are extremely wide-ranging, playing an important role in many sectors such as industry, civil use, and military industry, as well as in many fields of scientific research. They are most commonly used in the chemical and petrochemical industries, with pressure vessels used in the petrochemical industry accounting for about 50% of the total number of pressure vessels. In the chemical and petrochemical fields, pressure vessels are mainly used for heat transfer, mass transfer, and reaction processes, as well as for storing and transporting pressurized gases or liquefied gases; they also have wide applications in other industrial and civil fields.
Pressure vessels are classified into the following four types based on their functions:
       1. Reaction Pressure Vessel (Code R), mainly used to complete the physical and chemical reactions of the medium, such as reactors, reaction kettles, polymerization kettles, synthesis towers, reforming furnaces, and gas generators;
       2. Heat Exchange Pressure Vessel (Code E), mainly used to complete the heat exchange of the medium, such as various heat exchangers, coolers, condensers, and evaporators;

       3. Separation Pressure Vessel (Code S), mainly used to stabilize fluid pressure and purify and separate gases, such as various separators, filters, oil collectors, scrubbers, absorption towers, copper washing towers, drying towers, steam stripping towers, steam cylinders, and deoxygenators;

       4. Storage Pressure Vessel (Code C, with spherical tanks coded as B), mainly used for storing or holding gases, liquids, and liquefied gases, such as various types of storage tanks.

       Hubei Xianghua Mechanical Equipment Co., Ltd. is a high-tech joint-stock enterprise restructured from the Xiangfan Chemical Machinery Factory established in 1969. It mainly engages in the comprehensive treatment of waste mineral oil turnkey projects (EPC). It is a manufacturer of equipment for industries such as pressure vessels, petrochemicals, pharmaceuticals, new energy, environmental wastewater purification, fertilizers, and industrial refrigeration in northwestern Hubei, and also has the capability for equipment installation and commissioning. The company has established an industry-standard oil and water quality analysis laboratory, capable of experimental analysis of various complex waste mineral oil raw materials and water quality conditions, possessing overall project industrial design capabilities. It has successfully built and put into production for many clients nationwide, achieving standards in one-time trial runs and receiving unanimous praise from customers.
